This page has links to several different photography- and Photoshop-related pages that will help you learn more about taking better pictures and becoming better photo editors.
I am also including copies of the presentation I gave April 12, 2023 on photography basics for your reference.
The Libraries has several Adobe CC licenses available for students to check out. It's getting toward the end of the semester and they are in high demand, so you may have to plan ahead a bit to make sure you can get access to one if you want to use it. If you aren't able to check out one of these, many of the desktop computers in King Library and the Art & Architecture Library have the Adobe suite available for you to use.
The below links will take you to different tutorials from Adobe that will help you get started with some simple photo editing and processing.
